GILLETTE SAFETY RAZOR OF DELAWARE COMPANY, OF BOSTON, MASSACHUSETTS, ACORPORATION SAFETY Razon- Application led February 9, 1928. Serial No.252,996.

Safety razors of the well known Gillette type are provided with a guardmember, a backing member and a blade between said members, and withmeans to detachably clamp the blade between the two members with theedges of the blade in shaving relation to the guard. The aforesaid partsof the-razor are detachable so that when it is desired to clean theblade the members are separated and the blade is removed, washed andwiped, which requires individual handling of the blade entirely separatefrom any of the other razor parts.

An object of my invention is to provide a l5 safety razor of the classhaving two clamping members to retain a blade between them with meanspivotally connecting the blade with one of said members so that when therazor is to be cleaned the clamping members may be separated and theblade may be swung on its pivot or hingeto one side of the member towhich it is plvoted in position to be washed and wiped while retained bysaid member, and whereby the blade may be swung back on its supportingmember and the other member may be applied upon the blade, means beingprovided to retain the blade clamped between the members.

Another object of my invention is to provide means cooperative betweenthe blade and one of its members for detachably pivotally connecting theblade with said member to permit ready replacement of blades in therazor.

My invention comprises novel details of improvement that will be morefully hereinafter pointed out and then set forth in the claims.

Reference is to be had to the accompanying drawings forming a parthereof, wherein Fig. l is a perspective view of a safety razor embodyingmy invention, showing the parts in shaving relation; Y

Fig. 2 is a vertical cross section of the razor;

Fig. 3 is a detail sectional view at 'right angles to Fig. 2;

Fig. 4 is a sectional detail showing the parts partly separated;

teeth 3 on opposite sides, said parts being mainly substantially in theform of the well 'known Gillette razor, adapted to clamp a blade 4therebetween. The blade 4 is pivotall'y detachably attached to one ofthe members l, 2 and of such dimension as to lie properly7` between saidmembers with the cutting edges of the blade in shaving relation to theguard teeth. The blade is shown provided at one end with a projection 5having laterally disposed `pivotal portions 5a, shown in T-head form,the narrow portion being between the blade and the lateral portions 5a,(Fig. 8) One of the clamping members, by preference the guard member l,is provided with keepers 6 for the projecting portions 5, 5a of theblade, which keepers are shown inthe form of eyes which may be formed onor secured to member 1 and are curled so as to form pivotal connectionsfor the blade. Said keepers are shown spaced apart to permit the narrowshank portion of projection 5 to operate between the keepers with thelateral portions 5a within the eyes of the keepers, whereby the blade ispivotally attached to the blade clamping member. To permit readyconnection of the pivotal portions 5', 5a of the blade with the keepers6 the inner edges of the latter are shown slotted at 6a, which enablesthe blade to be attached to the keepers by tucking one of the portions5a through the space between the keepers and into the eye of one of thekeepers, when the blade is positioned at an angle to the plane of member1, and then the blade may be straightened out over said member and theother portion 5a will pass through the slot 6a of the other keeper andenter the eye of the latter, whereby the blade will be pivotallvattached to member 1. To remove the blade from member 1 the blade may beturned edgewise to withdraw one of the portions 5a through a slot 6a ofa keeper, and then the other pivotal portion 5a of the blade may bedetached from the other keeper.

By preferencel the members 1 and 2 are pivotally connected together at`their ends opposite the keepers 6. For such purpose l have shown theguard member 1 provided with a hinge vextension 7 through which a pivotpin 8 passes, and the member 2 is provided with spaced hinge-likeprojections 9 located on opposite sides of the extension 7 and providedwith openings 10 receiving the pivot pin 8, whereby the members 1 and 2are hinged together and kept from lateral displacement. By preferencethe openings 10\are elongated in slot-like form, to permit the members 1and 2 to have adjustment more or less closely with respect to oneanother and with relation to blade 4 therebetween. To keep the free endof blade 4 from lateral movement between members 1 and 2 said blade isprovided with a projection 11 extending from one end of the bladebetween its two cutting edges 4, which projection is adapted to enterthe space between the hingelike projections 9 and to engage the same tokeep the blade edges aligned with respect to the guard teeth 3 whenmember 2 is closed upon the blade, (Fig. 5). The end of member 2,opposite the pivot 7, is shown provided with spaced fingers or lugs 12that are adapted to pass over the adjacent ends of the blade andthemember 1 and to bear against the outer sides of the keepers 6 to retainthe member 2 from lateral movement respecting the blade when the partsare clamped together.

lAny suitable means may be provided for clamping the members 1 and 2against blade 4. For such purpose ll have shown member 2 provided with athreaded Vstud 13 adapted to pass through an .opening 4a in the bladeand to be engaged by anv internally threaded bore. 14 in a rod 15 thatisoperable'in a bore 16a in handle 16 that is attached to member 1, ashoulder 15a on rod 15 being adapted to engage the outer end of handle16, whereby when the parts are assembled, as shown in Fig. 2, and therod 15 is rotated to engage the threads at 13 and 14 the members 1 and 2may be clamped upon the blade to retain the latter in shaving relationto the guard teeth, in a well known way.

lin the modification shown in Fig. 8 the members 1 and 2 are not hingedtogether, although the blade 4 is pivotally and detachably connected tomember 1 in the manner :Lesesaal in the manner of the well knownGillettev razor.

When the parts are in the position shown in Figs. 1 and 2 and it isdesired to clean and dry the blade the rod 15 is unscrewed from the stud13 and the member 2 is removed from over the blade, either by swingingout on its hinge, as in Figs. 1 to 7 or by removing member 2 entirely,as in Fig. 8, and then the blade 4 may be swung to one side of member 2,as illustrated in Fig. 5, without detaching the blade from the razorframe. The blade may then be washed and wiped and swung over upon member1 to be clamped between members 1 and 2, as before set forth. When theblade is to be replaced it is merely necessary to detach its pivotalprojections 5, 5a from the keepers 6 and re-attach another blade.

An advantage of my invention is that it is not necessary to manuallylift the blade for cleaning and replacement and thereby danger ofcutting the fingers attendant upon such operations is reduced.

Changes may be made in the details of construction and arrangement ofparts set forth, within the scope of the appended claims, withoutdeparting from the spirit of my invention.
